基于MCR和重力模型的传统村落自然-文化生态网络识别与保护策略研究OA

[Purposes]In the dual-background of ecological civilization construction and concen-trated contiguous protection of traditional villages,in this study,the challenges of impaired landscape continuity and insufficient synergy of ecological functions in traditional villages are addressed by taking Xiaoyi City in Shanxi Province as a case study.[Methods]First,a comprehensive evaluation method was employed to assess the natural-cultural ecological value of traditional village nodes.Subsequent-ly,fourteen key factors were selected from the three dimensions of natural environment,socioeconom-ic conditions,and service facilities,and the analytic hierarchy process was applied to determine their weights and construct an integrated composite resistance surface.The minimum cumulative resistance model was then used to identify ecological corridors,and the gravity model was further applied to clas-sify these corridors into hierarchical levels.Finally,a traditional village ecological network character-ized by a"three-level node and three-level corridor"structure was identified.[Results]The results show that ecological resistance in the study area exhibits a pattern of being high in the northwest and low in the southeast.Traditional villages are predominantly located in medium-to low-resistance ar-eas,which are conducive to constructing a low-cost ecological flow network structure.Core nodes and corridors are mainly concentrated on the northern side of Shengxi Lake,while the remaining nodes and corridors are evenly distributed and extensively connected,forming a secondary network.Through the identification and optimization of the traditional village ecological network,this study pro-vides a scientific basis for the contiguous conservation and sustainable ecological development of tradi-tional villages.
